Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you.

We are looking to add a Principal RF Engineer I to our team. The ideal candidate has extensive experience in board-level and system-level RF electronics design. If you enjoy working in a startup environment and are passionate about developing leading-edge phased arrays for satellites, spacecraft, and aerospace systems, we would like to hear from you.

In this position, you will be responsible for RF circuits, modules, and systems through all phases of the development process. The ideal candidate will be proficient in board-level schematic design and PCB layout of RF circuits, system-level communications concepts such as link budgets and modulation schemes, and end-to-end RF product development. The work will include many aspects of phased array communication systems, including RF front ends, frequency converters and synthesizers, filters, beamformers, power dividers, and phased array antennas.

As a principal hardware team member, you will be responsible for RF system and hardware designs from initial concept through requirements definition, architecture definition, part selection, detailed design, analysis, manufacturing, testing, qualification, and in-orbit support of Cesium’s products. Hardware design tasks will include block diagrams, detailed schematics, PCB layout and routing, simulations, and test design. Principal engineers also serve as technical and professional mentors in their field and may be given the opportunity to lead company programs.

The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
